The chemiluminescence (CL) reaction was observed from the synthesized N-tetrahydrobenzothiazolyl imines mixed with acidified potassium permanganate and the emission intensity was significantly enhanced, when the formic acid was added. The fluorescence spectra, CL spectra, UV-VIS absorption spectra and kinetic property of the reaction were investigated. Based on the CL reaction, a flow injection method for the determination of Ntetrahydrobenzothiazolyl imine was developed. The relative standard deviation for eleven replicate injections of 1.0× 10-6 mol/L schiff bases of N-tetrahydrobenzothiazolyl imine was 1.7%, and the detection limit (3σ) was 5.0 ×10-8 mol/L. Mn2+ ,Fe3+ ,Cu2+ ,Ni2+ ,Cr3+ ,Mg2+ ,Zn2+ ,Tl+ ,Bi2+ and Al3+ ions had no effect whilst Ag+ and Fe2+ ions interfered with the determination.
